FIELD

This disclosure relates to the field of mirror support brackets. More particularly, this disclosure relates to an adjustable mirror bracket for supporting a mirror on a watercraft.

BACKGROUND

Recreational watercraft frequently include one or more mirrors mounted near an operator of the watercraft such that the driver of the watercraft can view a water skier, wakeboarder, or wake surfer behind the watercraft. Placement of the mirror is important in that it should allow an operator of the watercraft to maintain a clear view of a person being towed by the watercraft while also placing the mirror in a position that does not obstruct a forward view of the watercraft operator.

To place the mirror in a desired position, attempts have been made to provide adjustable mirrors that include a hinge or other assembly to allow a mirror to pivot or otherwise adjust. However, these attempts provide limited adjustment of the mirror. Further, traditional pivots or hinges may reduce stability of the mirror resulting in shaking or movement of the mirror during operation of the watercraft, thereby making viewing of a person being towed by the watercraft difficult. Finally, mirrors that may provide adjustability include multiple visible fasteners and components that reduce an appearance of the mirror or support components.

What is needed, therefore, is an adjustable mirror bracket that provides adjustment of a rearward facing mirror along multiple axes and that supports a mirror in multiple positions.

DETAILED DESCRIPTION

Various terms used herein are intended to have particular meanings. Some of these terms are defined below for the purpose of clarity. The definitions given below are meant to cover all forms of the words being defined (e.g., singular, plural, present tense, past tense). If the definition of any term below diverges from the commonly understood and/or dictionary definition of such term, the definitions below control.

An adjustable mirror bracket 10 is provided for attaching a rear-facing mirror to a watercraft. The adjustable mirror bracket supports the mirror in a position relative to an operator of the watercraft such that the operator may have a rearward view from the watercraft without obstructing the operator's forward-facing view. The adjustable mirror bracket 10 enables a user to adjust a position of a mirror supported by the bracket along multiple axes such that the mirror may be appropriately positioned on a variety of surfaces of a watercraft and in various orientations.

FIG. 1 shows a basic embodiment of the adjustable mirror bracket 10. The mirror bracket 10 includes a base member 12 and a pivot member 14 adjustably engaged with the base member 12. A spherical bearing 16 (FIG. 2) including a projecting stud 18 is at least partially disposed within base member 12 for attaching the pivot member 14 to the base member 12. An elongate support arm 20 is pivotally attached to the pivot member 14 at one end, and a mirror 22 is attached at a second end of the elongate support arm 20. The adjustable mirror bracket 10 enables multi-axis and multi-plane adjustment of the mirror 22 with respect to a surface on which the adjustable mirror bracket 10 is mounted.

Referring now to FIGS. 3 and 4, the base member 12 is formed of a cylindrical body 24 having a bottom end 26 and a top end 28. The bottom end 26 of the base member 12 is preferably substantially flat, such that the base member 12 may be attached to a surface around or near a dash of a watercraft. The base member 12 may be secured to a watercraft using one or more fasteners extending through one or more mounting holes 30 formed through the cylindrical body 24 of the base member 12 and into a surface of the watercraft. The top end 28 of the body 24 has a hemispherical or rounded shape, as shown in FIG. 4.

The cylindrical body 24 is preferably formed of a solid metal, such as steel or aluminum, however it is also understood that various other suitable materials such as a polymer or composite material may be used. Further, while the above description contemplates a cylindrical body of the base member 12, it is also understood that the body of the base member 12 may be formed into a variety of other shapes.

A socket 32 is formed within the cylindrical body 24 for engaging the spherical bearing 16 and projecting stud 18, as shown in FIG. 5. Referring to FIG. 4, the socket 32 has a substantially hourglass shape such that a diameter of the socket 32 tapers from a width at the bottom end 26 to a narrower middle portion 34 before again tapering outward to a width at the top end 28 of the cylindrical body 24.

With continued reference to FIG. 4, the socket 32 is shaped to conform to a surface of the spherical bearing 16 such that the spherical bearing 16 may move in relation to the socket 32. The narrower middle portion 34 has a width that is less than a diameter of the spherical bearing 16 to substantially prevent the spherical bearing 16 from moving upward through the base member 12. The stud 18 of the spherical bearing 16 extends substantially upward through the base member 12 and projects from the top end 28 of the base member 12 when the spherical bearing 16 is positioned within the socket 32. The spherical bearing stud 18 preferably includes a threaded portion 36 extending above the top end 28 of the base member 12, and also includes a keyed portion 37 having a rectangular or other shaped cross-sectional area.

The spherical bearing 16 is preferably formed of a molded polymer. The spherical bearing 16 may include a stud body portion 39 that is formed on the spherical bearing 16. The stud body portion 39 is preferably molded with the spherical bearing 16 such that the spherical bearing 16 and study body portion 39 are formed of a single piece. The keyed portion 37 is also preferably molded as part of the study body portion 39 during molding of the spherical bearing 16 and stud body portion 39. The threaded portion 36 is preferably formed of a bolt or other insert made from steel or other suitable metal materials over which the stud body portion 39 and spherical bearing 16 are molded, wherein part of the threaded portion 36 extends from the stud body portion 39. While the spherical bearing 16 is preferably molded with the stud body portion 39 and keyed portion 37, it is also understood that the spherical bearing 16 may be formed of a metal such as steel, aluminum, or other suitable metals, and that the study body portion 39 may be formed separately and attached to the spherical bearing 16.

Referring to FIGS. 6 and 7, the pivot member 14 includes a cylindrical bottom end 38 and an attachment surface 40 formed along an upper end 42 of the pivot member. A cupped portion 44 is formed in the bottom end 38 of the pivot member 14, the cupped portion 44 having a shape that substantially conforms to the hemispherical top end 28 of the base member 12. An attachment bore 46 is formed through the cupped portion 44 of the pivot member 14 for receiving the stud 18 of the spherical bearing 16. A keyed recess 48 may also be formed in the bottom end 38 of the pivot member 14 for engaging the keyed portion 37 of the stud 18.

The pivot member 14 includes a body portion having a hemispherical cross-sectional area. The attachment surface 40 is formed along a flat back portion of the body. A cavity 50 is formed in the attachment surface 40 and extends into the body portion of the pivot member. The cavity 50 intersects with the attachment bore 46 such that when the pivot member 14 is engaged with the base member 12, the threaded portion 36 of the stud 18 extends into the cavity 50 of the pivot member 14. A nut or other like fastener is inserted into the cavity 50 and attached to the stud 18 to secure the pivot member 14 to the base member 12. A threaded support arm bore 52 is also formed in the body of the pivot member 14 for receiving a threaded fastener. The pivot member 14 is also preferably formed of a metal such as steel or aluminum, however, it is also understood that the pivot member 14 may be formed of other suitable metallic and non-metallic materials, such as a polymer or composite material.

The attachment surface 40 provides a substantially flat surface for engaging a surface of the elongate support arm 20. Referring to FIG. 8, the elongate support arm 20 includes a first arm end 54 and a second arm end 56 that is distal from the first arm end. A bore 58 is formed on the first arm end 54 of the support arm 20 and is aligned with the support arm bore 52 of the pivot member 14. A guide track 60 may also be formed towards the first arm end 54 of the support arm 20 for engaging a portion of the pivot member 14 and limiting an angle at which the support arm 20 pivots with respect to the pivot member 14.

The support arm 20 is pivotally attached to the pivot member 14 with a threaded fastener 62, as illustrated in FIG. 9. The threaded fastener 62 includes a knob 64 that allows a user to threadably engage the support arm 20 to the pivot member 14 to prevent rotation of the support arm 20 with respect to the pivot member 14. While the fastener preferably includes a knob 64 or other like surface allowing a user to tighten or loosen the threaded fastener 62, other various fasteners may be used that require a tool for adjustment. Similarly, other suitable fasteners may be provided that allow a user to manually engage or disengage the support arm 20 from the pivot member 14.

In one embodiment, the attachment surface 40 of the pivot member 14 includes a serrated surface or includes raised portions extending from the attachment surface. The support arm 20 also includes a serrated surface or raised portions that corresponds to the serrated surface or raised portions of the attachment surface. The serrated surfaces or raised portions interlock when the threaded fastener 62 is tightened, thereby further preventing the support arm 20 from pivoting with respect to the pivot member 14.

Referring again to FIG. 1 the mirror 22 is pivotally attached to the support arm 20 at the second arm end 56. A suitable mirror is illustrated, for example, in U.S. D712,325. The mirror includes a reflective surface within a field of view of an operator of the watercraft such that the operator is presented a rearward-facing view from the watercraft during operation. As illustrated in FIG. 10, a threaded fastener 66 extends through the second arm end 56 and into a back of the mirror 22 for securing the mirror 22 to the support arm 20. Adjustment of the mirror 22 relative to the support arm 20 is possible using an adjustable pivot or joint between the mirror 22 and support arm 20. In one embodiment the mirror 22 is attached to the support arm 20 with a mirror ball joint that allows the mirror 22 to rotate and pivot along multiple axes. The threaded fastener engages the mirror ball joint such that when the fastener 66 is loosened the mirror 22 is adjustable relative to the support arm 20, and when the fastener 66 is tightened the mirror 22 is maintained in a desired position relative to the support arm.

The adjustable mirror bracket 10 allows a user to position the mirror 22 in a desired position on a watercraft so that an operator of the watercraft has a clear rear-facing view from the watercraft with the mirror 22. In operation, the base member 12 is attached to a surface of the watercraft adjacent a position of the operator. The base member 12 may be attached to a surface such as a dash area of the watercraft. The surface may be oriented in a substantially horizontal or vertical position prior to adjusting a position of the mirror 22 as discussed in detail below. The base member 12 is attached to the surface by inserting one or more fasteners through the one or more mounting holes 30 of the base member 12. The fasteners extend through the mounting holes and into a mounting surface on the watercraft. The fasteners secure the base member 12 to the watercraft using one or more nuts that engage the fasteners extending through the base member 12.

Prior to attaching the base member 12 to a surface of the watercraft, the spherical bearing 16 is disposed within the socket 32 of the base member 12 such that the spherical bearing stud 18 extends from a top portion of the base member 12. The pivot member 14 is placed over the base member 12 such that the spherical bearing stud 18 extends through the attachment bore 46 and into the cavity 50 of the pivot member 14. A nut or other fastener is inserted into the cavity 50 and engages the threaded portion 36 of the stud 18. When the pivot member 14 is secured to the base member 12, the keyed portion 37 of the stud 18 engages the keyed recess 48 of the pivot member 14 such that the pivot member 14 and spherical bearing 16 rotate together.

When a user desires to re-orient the pivot member, the fastener retaining the spherical bearing stud 18 is substantially loosened, thereby allowing the pivot member 14 to move in multiple planes (such as forward/backward and side to side movement) and further allows the pivot member 14 to be rotated with respect to the base member 12. Movement of the pivot member 14 is limited by the stud 18 of the spherical bearing 16 contacting one or more walls of the socket 32 in the base member 12. When the pivot member 14 is in a desired position relative to the base member 12, the nut engaging the spherical bearing stud 18 is tightened, thereby securing the pivot member 14 to the base member 12 in the desired position.

After positioning the pivot member 14 in a desired orientation, the support arm 20 is attached to the pivot member 14 using threaded fastener 62. The threaded fastener 62 extends through the first end 54 of the support arm 20 and into the support arm bore 52 of the pivot member. A user adjusts an angle of the support arm 20 relative to the pivot member 14 until the support arm 20 is in a desired position. After placing the support arm 20 in a desired position, a user tightens the fastener 62 using knob 64, thereby securing the orientation of the support arm 20 with respect to the pivot member 14. When the support arm 20 is attached to the pivot member 14, the first end 54 of the support arm 20 substantially conceals the cavity 50 and fastener placed therein.

After securing the support arm 20, the mirror 22 is attached to the second end 56 of the support arm 20 using threaded fastener 66. An orientation of the mirror 22, which preferably includes a ball joint, is then adjusted such that an operator of the watercraft may obtain an unobstructed rear-facing view from the watercraft. An angle and rotation of the mirror 22 are adjusted until the mirror is in a desired position. The threaded fastener 66 is then tightened to secure the mirror 22 in the desired position.

The adjustable mirror bracket of the present disclosure advantageously enables a user to secure a mirror to a watercraft such that the mirror is supported in a variety of configurations. The user may attach a base of the bracket to an angled surface and orient the pivot member and support arm into a variety of positions depending on where the mirror is needed to provide the operator with a rearward-facing view from the watercraft. FIGS. 11-16 illustrate the adjustable mirror bracket 10 of the present disclosure oriented in various configurations. The adjustable attachment of the pivot member to the base member, support arm to the pivot member, and mirror to the support arm allows an orientation of the mirror to be adjustable in multiple axes relative to a surface on which the bracket is supported.

The mirror bracket of the present disclosure provides substantial adjustability while also providing a stable support for the mirror that prevents movement of the mirror during operation of the watercraft. After the mirror is adjusted into a desired position and fasteners securing the pivot member to the base member and support arm to the pivot member are tightened, the mirror is substantially prevented from moving.
